Description

Technical Field

[0001] This utility model relates to the field of nanofiber membrane and substrate composite technology, and in particular to a hot roller device for nanofiber membrane and substrate composite. Background Technology

[0002] Nanofiber membrane-substrate composite refers to combining nanofiber membrane with substrate through physical or chemical methods to form a multilayer structure material that combines the advantages of both. This process usually requires the use of a hot roller device, whose core function is to achieve a firm bond between the nanofiber membrane and the substrate through heating and pressurization: the hot roller controls the temperature to melt or soften the surface of the substrate, while the pressure promotes the embedding of nanofibers into the surface of the substrate to form a mechanically interlocked structure.

[0003] In the preparation of nanofiber composite membranes, hot rollers can laminate polyolefin substrates with nanofibers, solving the problem of easy detachment when directly composited. In flexible electronic devices, hot rollers can ensure stable adhesion between the nanofiber conductive layer and the elastic substrate, avoiding separation caused by mechanical stress. Through the synergistic effect of temperature and pressure, the hot roller device significantly improves the structural integrity and functional reliability of composite materials, making it a key process equipment for nanofiber membranes to move from the laboratory to industrial applications.

[0004] However, current hot roller devices are not convenient for quickly controlling the pressure of the hot rollers, which can easily lead to unstable composite quality. At the same time, they cannot adapt to different types of substrates, thus affecting production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a hot roller device for laminating nanofiber membranes with substrates, aiming to solve the technical problems of existing hot roller devices, which are not convenient for quickly controlling the pressure of the hot roller, thus easily leading to unstable composite quality, and also cannot adapt to different types of substrates, thereby affecting production efficiency.

[0006] To achieve the above objectives, this utility model employs a hot roller device for composite nanofiber membranes and substrates, comprising an upper support and a lower support. Four bidirectional screws are rotatably mounted on the outer sides of both the upper and lower supports, and an upper moving frame and a lower moving frame are threaded between the four bidirectional screws. Multiple upper hot roller bodies are rotatably mounted within the upper moving frame via bearings, and one end of each upper hot roller body is connected to multiple first synchronous pulleys via a first synchronous belt. One of the upper hot roller bodies is driven by a first motor. Multiple lower hot roller bodies are rotatably mounted within the lower moving frame via bearings, and one end of each lower hot roller body is connected to multiple second synchronous pulleys via a second synchronous belt. One of the lower hot roller bodies is driven by a second motor. The four bidirectional screws are connected via a third synchronous belt and multiple third synchronous pulleys, and one of the bidirectional screws is driven by a third motor. A mounting box is located below the lower support, and the third synchronous belt and multiple third synchronous pulleys are all located within the mounting box.

[0007] The upper bracket has a first protective box on its outer side, and the first synchronous belt and multiple first synchronous pulleys are located inside the first protective box. Multiple first limiting strips are provided inside the first protective box, and the multiple first limiting strips abut against the outer wall of the first synchronous belt.

[0008] The upper bracket has a first protective box on its outer side, and the first synchronous belt and multiple first synchronous pulleys are located inside the first protective box. Multiple first limiting strips are provided inside the first protective box, and the multiple first limiting strips abut against the outer wall of the first synchronous belt.

[0009] The plurality of upper heating roller bodies and the plurality of lower heating roller bodies are arranged symmetrically in the upper and lower positions, and all of the plurality of upper heating roller bodies and the plurality of lower heating roller bodies are electric heating rollers.

[0010] Two of the first synchronous pulleys are located at both ends of the first synchronous belt, and the remaining first synchronous pulleys are located on the inner wall of the first synchronous belt. Two of the second synchronous pulleys are located at both ends of the second synchronous belt, and the remaining second synchronous pulleys are located on the inner wall of the second synchronous belt.

[0011] This invention discloses a hot roller device for laminating nanofiber membranes with substrates. A third motor drives one of the bidirectional screws to rotate. A third synchronous belt and multiple third synchronous pulleys transmit the rotation of all four bidirectional screws synchronously, thereby driving the upper and lower moving frames to move relative to each other. This allows for rapid and precise control of the pressure between the upper and lower hot roller bodies, preventing unstable lamination quality due to pressure instability. Furthermore, the device can flexibly adjust the distance between the upper and lower hot roller bodies, adapting to substrates of different thicknesses and types to meet diverse production needs and improve production efficiency. The use of electrically heated rollers with symmetrical vertical arrangement, along with a well-designed layout of the first and second synchronous pulleys, further ensures stable operation and high lamination quality.

Detailed Implementation

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] Please see Figures 1 to 7 This utility model provides a hot roller device for composite nanofiber membranes and substrates, including an upper support 1 and a lower support 2. Four bidirectional screws 3 are rotatably arranged on the outer sides of both the upper support 1 and the lower support 2, and an upper movable frame 4 and a lower movable frame 5 are threaded between the four bidirectional screws 3. Multiple upper hot roller bodies 6 are rotatably arranged within the upper movable frame 4 via bearings, and one end of each upper hot roller body 6 is connected to multiple first synchronous pulleys 8 via a first synchronous belt 7. One of the upper hot roller bodies 6 is driven by a first motor 9. The lower movable frame 5... Multiple lower heating roller bodies 10 are rotatably arranged inside the bearing, and one end of each of the multiple lower heating roller bodies 10 is connected to multiple second synchronous pulleys 12 via a second synchronous belt 11. One of the lower heating roller bodies 10 is driven by a second motor 13. The four bidirectional screws 3 are driven by a third synchronous belt 14 and multiple third synchronous pulleys 15. One of the bidirectional screws 3 is driven by a third motor 16. A mounting box 17 is arranged below the lower bracket 2, and the third synchronous belt 14 and multiple third synchronous pulleys 15 are all located inside the mounting box 17.

[0023] In this embodiment, by setting the third motor 16 to drive one of the bidirectional screws 3 to rotate, and utilizing the transmission action of the third synchronous belt 14 and multiple third synchronous pulleys 15, the four bidirectional screws 3 can achieve synchronous rotation. The upper moving frame 4 and the lower moving frame 5 are respectively threadedly connected to the four bidirectional screws 3. When the bidirectional screws 3 rotate synchronously, the upper moving frame 4 and the lower moving frame 5 can be driven to move relative to each other, thereby quickly and accurately controlling the pressure between the upper hot roller body 6 and the lower hot roller body 10, effectively avoiding the problem of unstable composite quality caused by unstable pressure. Simultaneously, because it is possible to... By flexibly adjusting the distance between the upper heating roller body 6 and the lower heating roller body 10, this device can adapt well to substrates of different thicknesses and types, meet diverse production needs, and significantly improve production efficiency. In addition, the upper heating roller body 6 is connected to the first synchronous belt 7 and multiple first synchronous pulleys 8 and driven by the first motor 9, and the lower heating roller body 10 is connected to the second synchronous belt 11 and multiple second synchronous pulleys 12 and driven by the second motor 13. This transmission method ensures that the multiple upper heating roller bodies 6 and multiple lower heating roller bodies 10 can rotate synchronously, providing a foundation for the stable composite of nanofiber membrane and substrate.

[0024] Furthermore, a first protective box 18 is provided on the outer side of the upper bracket 1, and the first synchronous belt 7 and multiple first synchronous pulleys 8 are all located inside the first protective box 18. Multiple first limiting strips 19 are provided inside the first protective box 18, and multiple first limiting strips 19 abut against the outer wall of the first synchronous belt 7.

[0025] In this embodiment, the first limiting strip 19 can effectively limit the first synchronous belt 7, preventing problems such as deviation or loosening of the first synchronous belt 7 during operation, ensuring stable transmission between the first synchronous belt 7 and the first synchronous pulley 8, thereby ensuring the stability of the synchronous rotation of the upper heating roller body 6, which is beneficial to improving the composite quality of nanofiber membrane and substrate.

[0026] Furthermore, a second protective box 20 is provided on the outer side of the lower support 2, and the second synchronous belt 11 and multiple second synchronous pulleys 12 are all located inside the second protective box 20. Multiple second limiting strips 21 are provided inside the second protective box 20, and multiple second limiting strips 21 abut against the outer wall of the second synchronous belt 11.

[0027] In this embodiment, the second limiting strip 21 can precisely limit the second synchronous belt 11 to prevent it from deviating during operation, ensuring stable transmission between the second synchronous belt 11 and the second synchronous pulley 12, so that the lower hot roller body 10 can rotate synchronously and stably, working in coordination with the upper hot roller body 6 to further improve the composite quality.

[0028] Furthermore, the plurality of upper heating roller bodies 6 and the plurality of lower heating roller bodies 10 are arranged symmetrically in the upper and lower positions, and the plurality of upper heating roller bodies 6 and the plurality of lower heating roller bodies 10 are all electric heating rollers.

[0029] In this embodiment, this layout ensures that the nanofiber membrane and the substrate are subjected to uniform pressure and heat during the composite process, thus guaranteeing the uniformity and stability of the composite. At the same time, the multiple upper heating roller bodies 6 and the multiple lower heating roller bodies 10 are all electric heating rollers. The electric heating rollers can precisely control the heating temperature and flexibly adjust the heating temperature according to the characteristics of different substrates and nanofiber membranes to meet diverse production needs.

[0030] Furthermore, two of the first synchronous pulleys 8 are located at both ends of the first synchronous belt 7, and the remaining first synchronous pulleys 8 are all located on the inner wall of the first synchronous belt 7. Two of the second synchronous pulleys 12 are located at both ends of the second synchronous belt 11, and the remaining second synchronous pulleys 12 are all located on the inner wall of the second synchronous belt 11.

[0031] In this embodiment, this layout enables a reasonable transmission relationship between the first synchronous belt 7 and the multiple first synchronous pulleys 8, ensuring that the first synchronous belt 7 is subjected to uniform force during transmission, reducing slippage, and improving the stability and reliability of the transmission. This, in turn, ensures that the upper heating roller body 6 can rotate synchronously and stably. Similarly, with two of the second synchronous pulleys 12 located at both ends of the second synchronous belt 11 and the remaining second synchronous pulleys 12 located on the inner wall of the second synchronous belt 11, the transmission between the second synchronous belt 11 and the multiple second synchronous pulleys 12 is also more stable, ensuring the synchronous and stable rotation of the lower heating roller body 10, which is beneficial for the high-quality composite of the nanofiber membrane and the substrate.

[0032] When using this utility model, the third motor 16 starts and drives one of the bidirectional screws 3 to rotate. Through the transmission of the third synchronous belt 14 and multiple third synchronous pulleys 15, the four bidirectional screws 3 rotate synchronously, thereby driving the upper moving frame 4 and the lower moving frame 5 to move relative to each other, so as to precisely control the distance and pressure between the upper hot roller body 6 and the lower hot roller body 10 to adapt to different substrates. At the same time, the first motor 9 drives one of the upper hot roller bodies 6 to rotate. This upper hot roller body 6 drives the other upper hot roller bodies 6 to rotate synchronously with the help of the first synchronous belt 7 and multiple first synchronous pulleys 8. Motor 13 drives one of the lower heating roller bodies 10 to rotate. This lower heating roller body 10 drives the other lower heating roller bodies 10 to rotate synchronously through the second synchronous belt 11 and multiple second synchronous pulleys 12. Furthermore, multiple upper heating roller bodies 6 and lower heating roller bodies 10 arranged symmetrically are all electric heating rollers, which can be heated as needed. The nanofiber membrane and the substrate are laminated between the upper heating roller body 6 and the lower heating roller body 10 under heat and pressure. The first protective box 18 and the first limiting strip 19 ensure the stable transmission of the upper heating roller body 6, and the second protective box 20 and the second limiting strip 21 ensure the stable transmission of the lower heating roller body 10.

[0033] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
